Answer 1

Пошаговое объяснение:

$\left \{ {{ax+8y=a} \atop {6x+3ay=a+2}} \right.$

$\left \{ {{8y=a-ax} \atop {6x+3ay=a+2}} \right.$

$\left \{ {{y=\frac{a}{8}-\frac{ax}{8} } \atop {6x+3ay=a+2}} \right.$

$\left \{ {{y=\frac{a}{8}-\frac{ax}{8} } \atop {6x+3a*(\frac{a}{8}-\frac{ax}{8})=a+2}} \right.$

$\left \{ {{y=\frac{a}{8}-\frac{ax}{8} } \atop {6x+(\frac{3a^{2} }{8}-\frac{3a^{2}x }{8})=a+2}} \right.$

$\left \{ {{y=\frac{a}{8}-\frac{ax}{8} } \atop {6x+\frac{x}{8} =a+2}} \right.$

$\left \{ {{y=\frac{a}{8}-\frac{ax}{8} } \atop {6x+\frac{x}{8} =a+2 | * 8}} \right.$

$\left \{ {{y=\frac{a}{8}-\frac{ax}{8} } \atop {48x-x =8a+16}}\right.$

$\left \{ {{y=\frac{a}{8}-\frac{ax}{8} } \atop {47x=8a+16}}\right.$
